The 4 wheel drive will not engage on my 2006 dodge ram 1500

Just because the indicator doesn't light up doesn't mean it's not working properly. Engage the four-wheel-drive when you think it's supposed to be engaged then play vehicle and drive let off the break pedal and quickly steer to the right if you and less if you can't turn a very tight or if you hit the gas and it starts to jump the front in then you know it's in four-wheel-drive if that doesn't work then your electronic actuator is messing up and need to replace it. If you can engage four-wheel-drive high then there's nothing wrong with your four-wheel-drive

Hope someone can help me. I have a 2005 Ram 1500 4x4 with 2.5 front leveling kit and need both sway bar end links but can't them anywhere. The ones that came off measure 15.75 inches.
